    CFI 600 burndown, Anyone else melt theirs?
    Posted by sledhead on Wednesday, April 04, 2007 7:52 PM
      My CFI 6 burned down at partial throttle on the mag cylinder. My dealer found a trouble-code telling them there was low voltage to one of the injectors. But after trouble-shooting the code they found nothing wrong. Polaris told them to rebuild the motor,erase the codes, and wait for a fuel re-map that is supposed to solve the burn down issue.
      Now I'm not a two-stroke fuel injection expert, but it seems far fetched that a fuel re-map would solve a SINGLE cylinder burn down problem. I don't want to start a rant against Polaris but I have heard of at least two other people from another dealer have the same problem. One poor guy even burned his down twice! Anyone have similar issues and if so what did your dealer tell you? Or more importantly, what did Polaris tell your dealer?

    yes,it will partly solve the problem out cauze,the mag side area being hotter and leaner than any other cylinders,so that jug is most common to wear out faster on the rings and cylinders wall,piston skirt and such,a remap with the proper timing curve will avoid the chance detonation by alot.

    Lowrider,there is a difference between an engineered to run lean motor and an engine that was not assembled correctly. In the isolated cases that have been mentioned here and that I know happened at my dealer I will say Polaris QC has a problem. Go back to the mid 90's when 600 and 650 triples were burning down. In this day and age an engine can be made to run lean at 1/4-3/4 throttle where 95% of an engine is operated at. At WOT a little rich will not hurt. So to your answer. If Doo can run their sleds lean and still get great fuel mileage, meet EPA requirements and pt out some decent power then I know Polaris can do the same. They just have to get smarter.

    maybe the engineeers need to read more magazines then they will be as "smart" as tx340..or at least they will be just as mis informed as some seem to be...just remember..if you read it in a magazine it just has to be true....get's old hearing"i heard it from....my dealer...a friend of a friends sister etc etc etc...next  i wonder who will be crying because the new polaris sleds don't have a magazine rack so one can read about how their sled is doing...while driving down the trail.....

    I think a big problem today is fuel quality which can be a headach on 2 strokes when trying to make that much power from a 600. While its nice to get good fuel economy, I think its getting scary when manufactures keep pushing the envelope for more power also while maintaining good old 87 or who knows pump gas to run on. I'd rather err on the rich side given a choice what were putting in our tanks.

    tnt340,I have an 07' 600 cfi with 3214 trouble free miles. You claim quality control problems,I say this is one damn good sled. All I can say is if you think ski-doo is so great doo us all a favor and go buy one, because I'm personally sick of your whining on how good ski-doo is and how bad polaris is.

    MEDOCRITY BREEDS MEDORCRITY ITS CALLED COMPETIION GUYS. IF CAT DID NOT BRING THE SLIDERAIL OUT WE WOULD ALL BE RIDING BOGIE WHEELS STILL IF POLARIS DID NOT BRING OUT THE INDY 340 WE WOULD STILL BE RIDING LEAF SPRINGS IF DOO DID NOT BRING OUT SDI WE WOULD NOT BE HAVING THIS CONVERSATION. NO CFI YEAH I RODE AN 07 600 LX WITH CFI THIS WINTER. NO PROBLEMS FOR ME. BUT ....... SOME GUYS DID. I ALSO RODE AN IQ CRUISER THIS WINTER AND GUESS WHAT. IT BURNT DOWN 6 MILES DOWN THE TRAIL. TURNS OUT THE OIL COOLER HOSES WERE INSTALLED BACK TO FRONT AT ROSEAU. *** HAPPENS. I RIDE THEM THEN TALK ABOUT THEM. 3500 MILES THIS WINTER. ONLY REPORT WHAT I EXPERIENCE FIRST HAND. I SAY KEEP RAISING THE BAR; CAT,DOO ,YAMAHA, POLARIS. IT IMPROVES ALL THE SLEDS. BEEN RIDING POLARIS SINCE 1970 AND INTEND TO KEEP RIDING THEM.
